Planning Outlook
Strong wind (often gale force on high mountains), patchy rain, and some broader swathes of rain and wind will affect the country from mid-week into the weekend; most notable areas of rain on Wednesday and late Thursday overnight into Friday. A few bright glimpses here and there, but many high summits stay shrouded, particularly western hill groups where cloud will often reach lower slopes. A brief bright window for some on Saturday, but staying windy with scattered showers in northwest areas, rain returning later and into Sunday. The next week remains generally unsettled, and may well bring a deep low pressure systems with widespread gales and swathes of heavy rain. Beyond next week, indications of a more settled regime for a time.
